    Given:

    A parabola opens up or down and its vertex is at the point (h, v).

    To find:

    The equation of the parabola.

    Solution:

    A parabola opens up or down. It means it is a vertical parabola.

    The vertex form of a vertical parabola is

    [tex]y=a(x-h)^2+k[/tex]             …(i)

    Where, a is constant and (h,k) is vertex.

    The vertex of given parabola is at point (h,v). Putting h=h and k=v in (i), we get

    [tex]y=a(x-h)^2+v[/tex]

    The required equation of the parabola is [tex]y=a(x-h)^2+v[/tex].

    Therefore, the correct option is A.
